Inventor: YASUJE MIKAMI
IPC: C22B34/12
Filed: 1992-11-06
Granted: 1997-12-10
Abstract: FIELD: industrial inorganic syntheses. SUBSTANCE: invention relates to sulfuric acid utilized in titanium dioxide production and containing metal sulfates including iron sulfates. Method consists in that ferrous sulfate contained in acid is oxidized into ferric sulfate and then hydrochloric acid is added followed by extraction of metal ions with solvent. If titanium ions are present in initial acid, extraction of Fe and Ti ions is performed separately. Hydrochloric acid is taken in such amount as to ensure chloride ion concentration in solution equal to at least 4-fold iron ion concentration.

Granted: 1997-06-27
Abstract: FIELD: chemical industry, in particular, production of pigment concentrates applicable in dyeing of polymer compositions. SUBSTANCE: composition for dyeing of polymer contains polymer, plasticizer and dye. Used as polymer is butadiene-nitrile rubber. Plasticizer is used mainly in form of dibutyl phthalate. Content and type of dye depends on the color of composition. Dyeing substances are of inorganic and organic nature. Essential distinguishing feature of composition for dyeing of polymer is combined use of butadiene-nitrile rubber, dibuthyl phthalate and dye in the offered ratio. Composition of dyeing of polymer is prepared in rubber mixer at temperature of 80-90 C and granulated in worm machine. To dye flexible PVC, 5% of composition is added to 100% of flexible PVC. In so doing, composition modifies properties of cast PVC to improve PVC mechanical-and-physical and adhesive properties. Use of different composition-to-PVC ratios results in variation of PVC properties within the required range. Composition may be used for dyeing of divinyl-styrene thermoplastic rubbers. EFFECT: improved mechanical-and-physical properties of cast PVC systems, extended field of application, as it is applicable not only for dyeing of cast PVC systems, but thermoelastic tubbers as well, simple compounding and manufacture technology. 2 cl, 7 tbl
